Abstract: Here disclosed is a steam sprayer for use in ironing textile products including clothes, which is user-friendly and offers highly effective ironing. A vaporizing chamber generates steam by vaporizing water stored in a tank. A water-supplying unit supplies the vaporizing chamber with water. A steam-ejecting section spouts steam outside. The steam-ejecting section includes a ironing surface with high frictional resistance characteristics. When touching the ironing surface to clothes or other fabrics for ironing, pulling force caused by the frictional resistance, which is a preferable wrinkles-off effect. Thus, the steam sprayer can offer a synergistic effect brought by spouting steam and applying the pulling force to clothes, fixing the form of clothes neatly.

Abstract: An iron comprising a bottom member as an ironing face, which is provided with a plated metal film containing fluorine compound fine particles, so that the ironing face provides high surface hardness which shows less wear, good slidability and less generation of static electricity.

Abstract: An iron has a first base to be directly heated for increasing an amount of accumulated heat, a second base including a soleplate and a thermal resistance layer disposed between the bases. The thermal resistance layer has a greater heat resistance than the first base so that the first base heated by a heater can maintain a higher temperature than the second base. The iron of the present invention can increase an amount of accumulated heat, thereby extending not only an ironing period but also a period for spraying steam. If a weight of the iron is decreased, the iron still can hold approximately the same accumulated heat as a conventional iron so that a lightweight iron can be provided.

Abstract: An electric steam iron having a standard steam spray mode for spraying a standard quantity of steam and an enhanced steam spray mode for spraying an increased quantity of steam as compared with that afforded during the standard steam spray mode. This electric steam iron includes a soleplate having a heater mounted thereon for heating the soleplate and a vaporizing chamber defined therein, a handle disposed above the soleplate, a water tank unit for supplying water to the vaporizing chamber, and a nozzle disposed at a bottom of the water tank unit. The electric steam iron also includes a valving mechanism for selectively opening and closing the nozzle for controlling supply of water to the vaporizing chamber, and a pumping mechanism for supplying an increased quantity of water within the water tank unit towards the vaporizing chamber to accomplish the enhanced steam spray mode.

Abstract: This invention relates to a process for preparing a titanium oxide powder comprising heating titanium dioxide powder in an atmosphere of ammonia gas at a temperature of about 500.degree. C. to about 950.degree. C. The product powder is very fine, highly uniform in particle size and useful as an electrically conductive material. The powder is colored blue to black depending upon the process conditions and therefore is useful as a pigment, too.

Abstract: Novel 2-phenylimidazo[2,1-b]benzothiazole compounds shown by general formula I ##STR1## and the salts thereof, a process of producing the compounds, and pharmaceutical compositions containing the compounds.The compounds of this invention act on immune response, in particular, suppress a delayed type hypersensitivity reaction, and are useful as antiallergic agents, antirheumatics, therapeutic agents for autoimmune diseases, and suppressants of rejection at tissue transplantation and skin graft.
